OIL-CAN.

Specification of Letters Patent.

Patented June 18, 1907.

Application filed November10,l906. Serial No. 342,899.

To 0Z2) whom, it may concern.-

Be it known that we, WILLIAM ELLIs HAR- MON and THOMAS BOISARTHGOODPAS'IURE, citizens of the United States, residing at Houston, inthe-county of Harris and State of Texas, have invented a new and usefulOil-Can, of which the following is a specification.

This invention relates to containers for holding oils and otherinflammable or explosive materials, and the principal object is toprovide an exceedingly simple structure of a novel nature that can becheaply manufactured, will prohibit the free escape of gases and vaporsthat may arise from the contents, and prevent flames following suchgases into the interior of the receptacle, said structure at the sametime allowing the free discharge of the contents, the venting of thecontainer and also providing suitable means, whereby the oil or othermaterial can be conveniently introduced into the said container.

The preferred embodiment of the invention is illustrated in theaccompanying drawings, wherein Figure 1 is a vertical sectional viewthrough a can having the improvements thereon; Fig. 2 is a detailsectional view on the line 22 of Fig. 1; Fig. 3 is a sectional viewthrough the closure for the filling opening and vent, the parts thereofbeing shown separated in order to fully disclose the same.

Similar reference numerals refer to similar parts throughout the variousfigures of the drawings.

In the embodiment disclosed, a receptacle 4 is employed that may be ofany desired shape or formation. This receptacle is provided with anexterior trap pocket 5 disposed contiguous to its upper end andcomprising a downwardly tapered hood having a spaced side wall 6. Theouter and lower wall of this pocket consists of a spout 7 suitablysecured by solder or other means between the outer margins of the sidewall 6 and projecting above and beyond the hood, its outer endconstituting an outlet. The outlet is arranged to be closed by a cap 8that fits upon the end of the spout and is loosely secured thereto bymeans of a yoke 9 that is fastened to the spout and passes through aslot 10 in the cap. The lower and inner side of, the spout 7 has anopening 11 that communicates with the lower portion of the trap pocket.

The side wall of the can is furthermore provided with an opening 12communicating with the upper portion of the trap pocket above theopening 11, the opening 12 being preferably punched through thematerial, thereby forming an annular rib or boss, as shown, althoughthis is not at all essential.

The top 13 of the receptacle has a suitable filling opening 14surrounded by a nipple 15 provided with a threaded lower portion 16 andan upper threaded portion 17 of less diameter than the lower portion. Aclosure or cap 18 is threaded upon the reduced por tion 17 and has anouter wall 19 that is perforate. A disk or washer 20, inserted into thecap 18, is clamped between the outer wall 19 and the outer end of thethreaded portion 17. Said disk or washer extends across the perforationsof the outer wall and while permeable to air will prevent the passage offlame. It is preferably constructed of ordinary wieking. An outer cap 21is screwed upon the threaded portion 17 and covers the cap 18. The cap21 carries a packing washer 22 of leather or other suitable material andsaid packing washer 22 is movable with the cap 21 to a position to closethe perforations in the outer wall 19 of the cap 18. Said cap 21preferably has a vent opening 23 in one side.

The operation of the structure may be briefly described as follows:Under normal conditions or when the container is not in use, the cap Sis placed upon the end of the spout and the cap 17 is threaded down sothat its outer wall or the washer 22 closes the perforations in the cap18; To use the device, the cap 8 is detached from the spout, the cap 17partially unscrewed, thus carrying the washer 17 away from the cap 18 sothat the interior of the receptacle is in communication with the outerair through the perforations in the wall 19 and through the vent 23. Itwill thus be evident that if the container is tilted, the contents willflow through the opening 12 into the trap pocket 5 and thence throughthe spout 7. When the receptacle is returned to its normal position, theliquid in the spout 7 instead of returning into the receptacle 4, willbe caught in the pocket 5 and will thus seal the lower end of the spout7, cutting off any passage of gases from the interior of the'can throughthe spout. There is thus no danger of flames following the gas ICCdownwardly through the spout and coming into contact with the contentsof the receptacle. Moreover, while air can pass through the fillingopening to vent the receptacle, and gases can, perhaps, flow outwardlytherethrough, careful tests have shown that the flames will not passthrough the perforate wall 19 of the inner cap 18 to the permeable disk20, and even if said disk 20 becomes saturated with oil, there will onlybe a flame at the cap 18 until the disk is dried. Complete communicationcan, however, be cut off at any time by placing the cap 18 upon thespout 7 and screwing down the cap 21.

Having thus described our invention,what We claim as new and desire tosecure by Letters Patent, is

1. A container of the class described comprising a receptacle, a trappocket secured to one wall thereof, said wall having an openingcommunicating with the upper portion of the interior of said trappocket, said pocket hav ing spaced side walls and a delivery spoutfitted snugly between the side walls and con stituting a closure for thepocket below the said opening, said spout projecting from the trappocket and having an opening communicating with the pocket and disposedbelow the opening in the wall.

2. A container of the class described comprising a receptacle, a trappocket secured to one wall thereof and comprising a hood having an openside, said pocket having commu nication with the interior of thereceptacle, and a delivery spout constituting a closure for the openside of the pocket, said spout having an inlet communicating with thelower portion of the pocket, and an outlet that projects from saidpocket.

3. A container of the class described comprising a receptacle, a trappocket secured to one wall thereof and comprising a downwardly taperedhood having side walls, and a spout secured between the said walls andconstituting the outer lower wall of the pocket, said spout havingcommunication at its lower end and its inner side with the pocket, andsaid receptacle having communication with the pocket in rear of thespout and above the inlet thereof.

1. A container of the class described comprising a receptacle having afilling opening, a perforate detachable closure covering the opening,and a cap movably mounted on the receptacle and movable to positions torespectively cover and uncover the perforate portion of the closure,said cap having a vent opening that is in communication with theperforations of the closure when the same are uncovered.

5. A container of the class described comprising a receptacle having afilling opening and a nipple surrounding the same, a cap detachablymounted on the nipple and having a perforate wall, and a washerpermeable to air and clamped between the nipple and the perforate wallof the cap, said washer extending across and being in engagement withthe perforate Wall of the cap.

6. A container of the class described comprising a receptacle having afilling opening and a nipple surrounding the same, a perforate capdetaohably secured on the nipple, a washer permeable to air, clampedbetween the nipple and cap, said Washer extending across the perforateportion of the cap, and another detachable cap mounted on the nipple andmovable thereon to a position to close the perforate portion.

7. A container of the class described comprising receptacle providedwith a nipple having threaded portions of different diameters, a capthreaded on the smaller portion of the nipple and having a vent, andanother cap threaded on the larger portion of the nipple and movablethereon to a position to close the vent.

A container of the class described comprising a receptacle, a deliveryspout having a trap pocket, said receptacle being provided with. afilling opening, a nipple surrounding the opening and having threadedportions of difl'erentdiameters, a cap threaded on the smaller portionand having an outer wall that is perforate, a washer permeable to airextending across the perforate portion of the cap and clamped betweensaid cap and the outer end of the nipple, and another cap threaded onthe larger portion of the nipple and covering the first-mentioned cap,said latter cap being movable to a position to close the perforations inthe first-mentioned cap and having a vent opening in one side.

In testimony, that we claim the foregoing as our own, we have heretoaffixed our signatures in the presence of two witnesses.
